Macbeth, Act 5 Scene 6 — Summary & Analysis

What happens

Malcolm, Siward, and Macduff arrive with their army carrying branches from Birnam Wood. They drop the leafy disguises to reveal themselves. Malcolm assigns Siward and his son to lead the first assault while he and Macduff handle the remaining forces. Macduff calls for the trumpets to sound, and the army advances toward Dunsinane Castle to face Macbeth.

Why it matters

This brief scene marks the moment prophecy becomes physical reality. The witches promised Macbeth safety until "Birnam wood to high Dunsinane hill / Shall come"—a prediction that seemed impossible. Now, with soldiers carrying branches, the forest literally moves. What Macbeth dismissed as equivocation, a riddling impossibility, materializes before his castle. The scene dramatizes the gap between what seems safe and what is actually true, between language that sounds reassuring and the brutal facts of war. Malcolm's strategic decision to use the branches both fulfills the prophecy and shows practical military thinking: the branches disguise troop numbers and confuse enemy scouts.

The tone shifts from Scotland's internal chaos to organized, purposeful action. Malcolm's commands are clear and orderly—he distributes authority, assigns positions, and maintains discipline. Unlike Macbeth, who has become isolated and paranoid, Malcolm acts as a true leader, delegating to trusted men and taking personal responsibility. Macduff's call for the trumpets to "speak" signals that words—equivocation, witches' riddles, hollow boasts—give way to action. The drumming, the colors, the marching soldiers: all suggest the restoration of legitimate order. By the scene's end, the machinery of justice has begun its final turn toward Macbeth's defeat.
